The magic number is 100. A collection of fun activities, this guide provides educators with ideas for young mathematicians to practice counting to 100.

Here is a multiple choice question that would make a good assessment question. Algebra students are to look at the structure of the formula for a given radius of a cylinder and find the resulting radius when the height of the...

if you've ever had to guess how many items were in a jar, then this problem is for you! With a big jar full of red and white marbles, does picking a sample of 16 allow your learners to get a good estimate on the percentages of each...

Heads! A great way to practice probability is to flip a coin in class. The provided data allows your mathematicians to predict the probability of heads in ten coin flips. Bring coins to class and allow your own trial of heads or tails....

Challenge young mathematicians to buy classroom supplies by staying within the means of a $1,000 budget. The mathematical activity provides learners with the opportunity to decide what items from the supply list would benefit a class of...

Here is a resource that demonstrates growth and the initial state of an equation. In this case, your class will be looking at baseball collections. How many baseball cards did the collector start out with, and how many were added or...

Go beyond a traditional end-of-the-year survey and have your middle school pupils compile a portfolio of work illustrating their progression as a writer. 

Students visit Ellis Island Immigration Museum (as a field trip or a virtual visit) and pretend to be Italian immigrants to the United States. They write a journal entry detailing their first week in the United States. They interview an...

Does watching TV increase one's blood pressure? Assess student understanding of how study design dictates whether a conclusion of causation is warranted. Use this as a prompt for a small group or whole class discussion, or as a part of a...

A jar is filled with 1,500 marbles and customers of a bank can enter a contest to guess the correct percentage of blue marbles. How can an employee at the bank estimate the actual percentage without physically counting all 1,500 marbles?...

Round and round and round she goes. Where she stops, nobody knows. This activity uses a common arcade game of chance, the spinning wheel, as a platform for computing expected values, interpreting results, and applying this knowledge to...

This is a great idea for any social studies classroom to incorporate throughout the year as an ongoing project! Line your walls with a continuous strip of butcher paper to design a large timeline that you can add to as you cover...

Knowing the temperature coefficient allows for the calculation of voltage output at any temperature. Groups conduct an experiment to determine the effects of temperature on the power output of a solar panel. The teams alter the...

Make the most of your prom—with math! Pupils write and use a quadratic model to determine the optimal price of prom tickets. After determining the costs associated with the event, learners use a graph to analyze the break even point(s).

Life science laureates choose a plant or animal cell to construct a model of as an at-home project. This handout provides guidelines, suggested materials, and a grading rubric for their reference. A full-page letter to parents is also...
